Where would one buy alternative crank arms or crank sets for a bb3a BB?
I need to replace my crank arms with 165mm ones and I am having trouble locating anything online.

TIA

You can get adaptive bottom brackets that allow you to use a real Shimano crank. Another plus is that they actually thread together. https://wheelsmfg.com/bottom-bracket...ale-bb30a.html

Pretty sure an Easton crank uses the same 30mm bottom bracket.

Sadly easton does not do 165
Any thoughts on this guy ? https://rotoramerica.com/collections...32581448499279

Also any idea what the difference is between

I hope to put one of these on my synapse carbon

MSRP is pretty high for what it is, but you should be able to find a deal somewhere.

The bearings are different; angular contact vs. ABEC-3. Neither one will work with the 30mm spindle on that rotor crank.

I think I'll skip the rotor crank option and go with wheel manufacturing + shimano ultegra instead.... 150gr is not going to make a difference for me. Or hope that someone will have cheap set of 165 hollowgrams on ebay
